It is well known that different types of non-standard topological objects may have been
formed during initial Universe evolution, such as domain walls, cosmic strings and
monopoles [1]}, [2]}. The basic idea is that these topological defects
have formed as a result of a breakdown of local or global gauge symmetries. The simplest
model that gives rise to global monopole is described by the Lagrangian
\(L=\frac{1}{2}\partial _{\mu }\phi ^{a}\partial ^{\mu }\phi ^{a},\)
